We have in our labs Kingston's latest solid-state drives (SSDs) for PCs and laptops, the SSDNow V300 Series. Designed to replace the existing SSDNow V200 models, the V300 should offer sequential read and write speeds of around 450MB/s - somewhere between five and 10 times faster than a traditional mechanical hard drive.

The V300 SSDs use a customized LSI SandForce SF-2281 controller, along with 19nm NAND flash memory components for storing the data.

Based on a 2.5-in form factor, the V300 Series is available in 60GB, 120GB and 250GB capacities as either a bare drive or as an upgrade kit which includes a caddy, mounting bracket and software for transferring data from an existing hard drive or SSD.
